Understanding the core functional differences between different series of electric rack and pinion window openers is crucial when choosing one. Below is a comparison of two common series. Series A window openers have a 400mm stroke and a high thrust of up to 1000N, suitable for large windows or scenarios requiring high opening force. Their operating speed is relatively slow, approximately 10mm per minute, but their stability is excellent, ensuring smooth opening and closing of the window. Series B window openers have a shorter stroke of 200mm, but a faster operating speed of up to 20mm per minute, suitable for small windows requiring fast opening. Their thrust is 500N, sufficient for most small windows. In terms of protection rating, Series A reaches IP55, effectively protecting against dust and water, suitable for harsh outdoor environments; Series B has an IP44 protection rating, more suitable for indoor use. In addition, Series A features overload protection and obstacle detection stop function, providing better protection for windows and people; Series B excels in energy saving, effectively reducing energy consumption. By comparing the core functions of different series of electric rack and pinion window openers, you can make a more suitable selection based on your actual needs.
